In recent years, the J/ψ signal in heavy-ion collisions at the CERN SPS has attracted much
attention as a potential quark–gluon plasma signature. This review discusses the prediction …

We discuss the nuclear dependence of ψ and ψ′ production in hadron-nucleus interactions
as a function of longitudinal momentum fraction x F. Nuclear effects such as final-state …

This is a review article on the experimental data from high-energy collisions with nuclear
targets. The emphasis is on projectile energies higher than 5 0eV (per nucleon for ion …

The production of μ+ μ− pairs with large longitudinal momentum has been studied in π− N
collisions. The data confirm an earlier result that most of the pair production takes place via …

We present measurements of the differential cross section for the production of massive
muon pairs in 225-GeV/c π−-nucleus collisions. We have used the data between the ψ and …

Precise measurements of nuclear effects in the production of massive lepton pairs from
heavy targets by pion and proton beams would extend knowledge of the nuclear …

We discuss the design and performance of a large-acceptance double-magnet spectrometer
used in Fermilab Experiment 615. The apparatus was used to measure the properties of …

We have measured the atomic-mass dependence of the PT distribution of massive muon
pairs produced in 225-GeV/c π−-nucleus collisions at Fermilab. We find that< PT 2> is …

We have calculated the impact on the A dependence of direct photon production at large
transverse momenta (p T) of models that were used successfully to explain the EMC effect …
